Certain Excel commands allow the user to select a range of cells by clicking
on a "select cells" icon at the right side of an input box; see, for
example, the input for "Input Y Range" in Tools/Data Analysis/Regression. I
would like to be able to provide the same functionality in an application I
am developing as an XLL using C++. If it can be done using a call to
Excel12(), what is the function number? If not, is there another way? I
would also like to be able to provide the cell selector from within a
function written in VBA. Any help you can provide would be very much
appreciated. Thanks.
